FIELD OF THE INVENTION

The present invention relates to cosmetic compositions capable offorming a multilayer structure after application to a keratinousmaterial. Such compositions allow for benefits associated withmultilayer cosmetic products without having to engage in a multi-stepapplication process.

DISCUSSION OF THE BACKGROUND

Many cosmetic compositions, including pigmented cosmetics such asfoundations and lipsticks, have been formulated in an attempt to possesslong wearing properties upon application. Unfortunately, many of thesecompositions do not generally possess both goodlong-wear/transfer-resistance properties as well as good applicationproperties, good comfort properties and/or good appearance properties(for example, shine, gloss or matte properties).

For example, with respect to lip products, commercial productscontaining silicon resins such as MQ resins are known. Such products areknown to provide good long wear properties and/or transfer-resistance.However, such products possess poor application properties, poor feelupon application (for example, feel rough) and poor shine or glossproperties owing to the film formed by the MQ resin (for example, amatte appearance). Therefore, a second composition (topcoat) isseparately applied to such products to improve poor properties of thecompositions to make the products acceptable to consumers. Furthermore,the topcoat composition must be reapplied continually so that theproduct remains acceptable to consumers, meaning that the products areeffectively not “long-wearing” as they require constant maintenance andreapplication.

Also, with respect to foundations, such products can provide good longwear properties and/or transfer-resistance. However, suchlong-wearing/transfer-resistant products can possess poor applicationand/or feel upon properties application, as well as poor matteproperties.

Thus, there remains a need for improved “single step” cosmeticcompositions having improved cosmetic properties, particularly goodwear, feel, shine, gloss and/or matte characteristics upon application.

“Polymer” as used herein means a compound which is made up of at leasttwo monomers.

“Substituted” as used herein, means comprising at least one substituent.Non-limiting examples of substituents include atoms, such as oxygenatoms and nitrogen atoms, as well as functional groups, such as hydroxylgroups, ether groups, alkoxy groups, acyloxyalkyl groups, oxyalkylenegroups, polyoxyalkylene groups, carboxylic acid groups, amine groups,acylamino groups, amide groups, halogen containing groups, ester groups,thiol groups, sulphonate groups, thiosulphate groups, siloxane groups,hydroxyalkyl groups, and polysiloxane groups. The substituent(s) may befurther substituted.

“Volatile”, as used herein, means having a flash point of less thanabout 100° C.

“Non-volatile”, as used herein, means having a flash point of greaterthan about 100° C.

“Anhydrous” means the compositions contain less than 1% water.Preferably, the compositions of the present invention contain less than0.5% water, and most preferably no water.

“Transfer resistance” as used herein refers to the quality exhibited bycompositions that are not readily removed by contact with anothermaterial, such as, for example, a glass, lips, skin or artificial skin,for example, when eating or drinking. Transfer resistance may beevaluated by any method known in the art for evaluating such. Forexample, transfer resistance of a composition may be evaluated by a“kiss” test. The “kiss” test may involve application of the compositionto human keratin material such as lips followed by kissing anothermaterial, for example, a glass, lips, skin or artificial skin, againstthe lips after expiration of a certain amount of time followingapplication, such as 15 minutes after application. The amount ofcomposition transferred to the substrate may then be evaluated andcompared. For example, a composition may be transfer resistant if amajority of the product is left on the wearer's lips. Further, theamount transferred may be compared with that transferred by othercompositions, such as commercially available compositions. In apreferred embodiment of the present invention, little or no compositionis transferred to the substrate from the lips.

“Gloss” in compositions as used herein refers to compositions havingwith an average gloss, measured at 60°, of greater than or equal to 35,for example 40, preferably 45, 55, 60 or 65 out of 100, including allranges and subranges therebetween such as 35-65, 40-65, etc.

The term “average gloss” denotes the gloss as it can be measured using agloss meter, for example by spreading a layer of the composition to betested, between 50 μm and 500 μm in thickness, on a Leneta contrast cardor BYK Opacity chart of reference Form 1A Penopac using an automaticspreader. The layer covers at least the white and/or black background ofthe card. The deposit is left to dry for 24 hours at a temperature ofroom temperature and then the gloss is measured at 60° on the whitebackground using a Byk Gardner gloss meter of reference microTRI-GLOSS.This measurement (of between 0 and 100) is repeated at least threetimes, and the average gloss is the average of the at least threemeasurements carried out.

“Adhesion” as used herein refers to the quality exhibited bycompositions that adhere to a substrate after application. Adhesion maybe evaluated by any method known in the art for evaluating such. Forexample, samples to be tested for adhesion properties can be depositedonto a surface such as a bioskin substrate. After drying, a piece ofASTM cross hatch tape can be placed on the sample, and removed at a 180°angle. Then, it can be determined how much of the sample is adhered tothe tape. For example, a rating scale such as a scale of 1-3 can be usedto assess the degree of sample removal from the substrate onto the tape,in which 1 is essentially no removal, 2 is some removal, and 3 isessentially complete removal.

“Tack” as used herein refers to the quality exhibited by compositionsthat adhere to an object after application to a substrate. Tack may beevaluated by any method known in the art for evaluating such, such asusing a texture analyzer. For example, a sample can be applied to asubstrate, allowed to dry, and contacted by an object such as a ½″stainless steel ball probe, after which the force associated withremoval of the object can be measured.

“Long wear” compositions as used herein, refers to compositions wherecolor remains the same or substantially the same as at the time ofapplication, as viewed by the naked eye, after an extended period oftime. Long wear properties may be evaluated by any method known in theart for evaluating such properties. For example, long wear may beevaluated by a test involving the application of a composition to lipsand evaluating the color of the composition after an extended period oftime. For example, the color of a composition may be evaluatedimmediately following application to lips and these characteristics maythen be re-evaluated and compared after a certain amount of time.Further, these characteristics may be evaluated with respect to othercompositions, such as commercially available compositions. Alternativelyor additionally, long wear properties may be evaluated by applying asample, allowing it to dry, and then abrading the sample to determineremoval/loss of sample.

The composition of the present invention may be in any form, eitherliquid or non-liquid (semi-solid, soft solid, solid, etc.). For example,it may be a paste, a solid, a gel, or a cream. The composition may be anemulsion, such as an oil-in-water or water-in-oil emulsion, a multipleemulsion, such as an oil-in-water-in-oil emulsion or awater-in-oil-in-water emulsion, or a solid, rigid or supple gel. Thecomposition of the invention may, for example, comprise an external orcontinuous fatty phase. The composition can also be a molded compositionor cast as a stick or a dish.

Compositions Capable of Forming a Multilayer Structure

In accordance with various embodiments of the present invention,cosmetic compositions capable of forming a multilayer structure afterapplication to a keratinous material are provided. Such compositionsallow for benefits associated with multilayer cosmetic products withouthaving to engage in a multi-step application process.

In accordance with the present invention, embodiments of the cosmeticcompositions of the present invention comprise at least two Components,hereinafter referred to as “Component A” and “Component B.” In furtherembodiments, both Component A and Component B comprise silicone.Component A, for example, may comprise a silicone-containingfilm-forming agent. Component B, for example, may comprise a siliconegum.

Component A is the component of the compositions of the presentinvention which forms the layer of the multilayer structure which isclosest to the keratinous material after application of the compositionto the keratinous material. This layer of the multilayer structure ishereinafter referred to as “Layer A.” In accordance with preferredembodiments, Component A/Layer A has an affinity for the surface of thekeratinous material owing to the surface energy characteristics betweenthe two.

Component B is the component of the compositions of the presentinvention which forms the layer of the multilayer structure which isfarthest away from the keratinous material after application of thecomposition to the keratinous material. This layer of the multilayerstructure is hereinafter referred to as “Layer B.” In accordance withpreferred embodiments, Component B/Layer B has an affinity for the airinterface.

In accordance with the present invention, all weight amounts and ratiosset forth herein referring to Component A and Component B refer toamounts of active material (that is, non-volatile material) in thesecomponents. Similarly, all weight amounts and ratios set forth hereinreferring to Layer A and Layer B refer to amounts of active material asLayer A and Layer B are present after evaporation of volatile solvent.

Prior to application to a keratinous material, Component A and ComponentB are immiscible in the compositions of the present invention.Preferably, immiscibility of the immiscible components results from anincompatibility between the two components when the composition is atrest, incompatibility between the two components after application to akeratinous material, or both.

In one or more embodiments, immiscibility of the immiscible componentsresults from differences such as, for example, differences in viscosity,glass transition temperature, interfacial tension, solubilityparameters, density, and/or chemical/structural incompatibility of thecomponents, and/or differences induced by temperature and/or pressure.

For example, immiscibility of the immiscible components when thecomposition is at rest can result from, for example, chemical/structuralincompatibility, differences in the interfacial tension between thecomponents such as, for example, differences in the interfacial tensionbetween the phases within mutually compatible solvent(s), differences inviscosity, differences in the glass transition temperatures of thepolymers within each phase and/or differences induced by temperatureand/or pressure.

For example, immiscibility of the immiscible components when thecomposition is being applied can result from, for example,chemical/structural incompatibility, differences in the interfacialtension between the components, differences in density of the componentsafter solvent evaporation, and/or differences induced by temperatureand/or pressure.

In one or more embodiments, immediately prior to application and/orduring application to a keratinous material, the composition of thepresent invention is mixed or blended such that Component A andComponent B are temporarily miscible upon application of the compositionof the present invention to a keratinous material.

After the composition of the present invention has been applied to akeratinous material, Component A separates from Component B. As thecomposition dries on the keratinous material to which it has beenapplied, immiscible Component A and Component B form a multilayerstructure comprising Layer A and Layer B, respectively, on thekeratinous material such as, for example:

LAYER B LAYER A KERATINOUS MATERIAL

According to one or more embodiments of the present invention, aftercompositions of the present invention have been applied to a keratinousmaterial, Component B results in Layer B which is level: that is, LayerB is planar such that it has refractive properties to impart shine orgloss to the composition. In accordance with these embodiments,Component B has self-leveling properties: it results in a level Layer Bafter application. The gloss or shine of such compositions can beenhanced, if desired, by addition of one or more shine or glossenhancing agents having high refractive index properties. Alternatively,such compositions can be provided with matte properties by addition ofone or more mattifying agents.

According to one or more embodiments of the present invention, aftercompositions of the present invention have been applied to a keratinousmaterial, Component B results in Layer B which is not-level: that is,Layer B is not planar such that it imparts matte properties to thecomposition. In accordance with these embodiments, Component B does nothave self-leveling properties: it results in a non-level Layer B afterapplication. The matte properties of such compositions can be enhanced,if desired, by addition of one or more mattifying agents. Alternatively,such compositions can be provided with shine or gloss properties byaddition of one or more shine or gloss enhancing agents having highrefractive index properties.

In accordance with the present invention, the multilayer structurecomprises Layer A and Layer B. In certain instances, depending onfactors such as ingredient ratios, ingredient concentrations, solventevaporation characteristics, and Tg of polymers, the layers might beintermixed slightly with each other after application to a keratinousmaterial, resulting in Layer A having a larger amount of A and a smalleramount of B greater and/or Layer B having a larger amount of B and asmaller amount of A. Preferably, Layer A comprises 40% or less of LayerB, preferably 30% or less of Layer B, preferably 20% or less of Layer B,preferably 10% or less of Layer B, and preferably 5% or less of Layer B,including all ranges and subranges therebetween. Similarly, preferably,Layer B comprises 40% or less of Layer A, preferably 30% or less ofLayer A, preferably 20% or less of Layer A, preferably 10% or less ofLayer B, and preferably 5% or less of Layer A, including all ranges andsubranges therebetween.

Factors affecting the separation of Component A and Component B afterapplication to a keratinous material can include, for example, thoseproperties discussed above including but not limited to the surfaceenergy of the substrate, the density of each Component, the evaporationproperties of the solvent(s), the Tg of the film formers, and/or theviscosity of the film formers.

Although not wishing to be bound by any particular theory, it isbelieved that Component A has a surface energy properties closer to thesurface energy properties of the keratinous material to which it isapplied than Component B. For example, the surface energy of skin isestimated to be 36 mN/m. Accordingly, where Component A has a surfaceenergy of about 36 mN/m, it is believed that Component A can migrate tothe skin. Component B would preferably have a lower surface energy,making it more likely that it would migrate toward the air interface.

Although not wishing to be bound by any particular theory, it isbelieved that interfacial tension of Components A and B affects phaseseparation (in particular, the rate at which the Components A and Bseparate after application). It is believed that such phase separationcan be affected by differences such as those discussed above such as,for example, differences in temperature of the Components A and B, inthe Tg of the Components A and B (the higher the Tg of a component, thelonger it will take for phase separation), in the weight fraction of thefilm formers, and/or in the pressure of the Components A and B.

Such differences will also be discussed further below.

According to preferred embodiments, Component A and/or Component Bcomprises at least one silicone-containing film forming agent having atleast one glass transition temperature lower than 60° C., preferablylower than 55° C., preferably lower than 50° C., and preferably lowerthan normal human body temperature (98.6° F. or 37° C.). Preferably,Component A and/or Component B comprises at least onesilicone-containing film forming agent which has all of its glasstransition temperature(s) below human body temperature (98.6° F. or 37°C.). A plasticizer can be added to adjust Tg of the film formingagent(s) as is known in the art. According to preferred embodiments,Layer A and Layer B both comprise at least one forming agent having aglass transition temperature of less than 37° C.

A preferred method of determining Tg is to remove all volatile solventfrom the Layer, and determining Tg by Differential Scanning calorimetry.

If present in Component B, the at least one polymer has Mc≤wMw≤108g/mol.

Further, according to preferred embodiments, the viscosity of the atleast one polymer in Component B is greater than 350 cSt, preferablygreater than 500 cSt, preferably greater than 750 cSt, and preferablygreater than 1000 cSt, including all ranges and subranges therebetween.

Ingredients

Component A and Component B can differ in various ways based primarilyon the different functionalities associated with Layer A and Layer B.For example, where Layer A performs a transfer-resistance or adherencefunction, ingredients of Component A can be chosen to effecttransfer-resistance or adherence. Similarly, where Layer A performs acolor-enhancing function, at least one coloring agent can be added toComponent A. And, for example, where Layer B performs a gloss- orshine-enhancing function and/or and provides a better feel (for example,affords a more comfortable feeling) and/or provides a barrier layer toinhibit color transfer, ingredients of Component B can be chosen toeffect gloss, shine, comfort and/or barrier layer properties. However,it should be understood that at the interface of Layer A and Layer B,the interface of Layer A may possess properties more associated withLayer B (for example, shine) while Layer B may possess properties moreassociated with Layer A (for example, adhesion).

According to preferred embodiments, Component A comprises at least onesilicone-containing film forming agent, at least one coloring agent, orboth, and Layer A provides adhesion, transfer-resistance and/or colorproperties to the multilayer structure. According to such embodiments,Component B may comprise at least one shine-enhancing agent, at leastone comfort agent and/or at least one barrier agent, and Layer Bprovides shine, comfort and/or a barrier properties to the multilayerstructure.

Silicone-Containing Film Forming Agent (Film Former)

Compositions of the present invention may comprise at least onesilicone-containing film forming agent. As used herein,“silicone-containing film forming agent” refers to a film forming agentthat contains silicone. In one or more embodiments, “silicone-containingfilm forming agent” includes polymers that contain at least about 2.5%,5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, or 99% silicone byweight. Silicone-containing film forming agents are known in the art,and any silicone-containing film forming agent may be used. According topreferred embodiments, at least one silicone-containing film formingagent having at least one glass transition temperature lower than 60°C., preferably lower than 55° C., preferably lower than 50° C., andpreferably lower than normal human body temperature (98.6° F.), isincluded in the composition of the present invention. Preferably, the atleast one silicone-containing film forming agent has all of its glasstransition temperature(s) below 60° C., preferably below than 55° C.,preferably below than 50° C., and preferably below than normal humanbody temperature (98.6° F.). The Tg property of the at least onesilicone-containing film forming agent can result from various waysknown in the art such as, for example, the Tg of the silicone-containingfilm forming agent itself, the combination of different film formingagents to achieve a Tg lower than normal human body temperature, or thecombination of film forming agent(s) and plasticizer(s) to achieve a Tglower than normal human body temperature.

Examples of acceptable classes of silicone-containing film formingagents include silicone resins, silicone acrylate copolymers. vinylpyrrolidone (VP) containing copolymers, polyurethanes, polyolefins andmixtures thereof.

In one or more embodiments, the silicone-containing film formingagent(s) is/are selected from the group consisting of silicone resins,silicone acrylate copolymers mixtures thereof.

Silicone Resin

As used herein, the term “resin” means a crosslinked or non-crosslinkedthree-dimensional structure. According to one or more embodiments of thepresent invention, Component A comprises at least one silicone acrylate.Silicone resin nomenclature is known in the art as “MDTQ” nomenclature,whereby a silicone resin is described according to the various monomericsiloxane units which make up the polymer.

Each letter of “MDTQ” denotes a different type of unit. The letter Mdenotes the monofunctional unit (CH₃)₃SiO_(1/2). This unit is consideredto be monofunctional because the silicone atom only shares on oxygenwhen the unit is part of a polymer. The “M” unit can be represented bythe following structure:

At least one of the methyl groups of the M unit may be replaced byanother group, e.g., to give a unit with formula [R(CH₃)₂]SiO_(1/2), asrepresented in the following structure:

wherein R is chosen from groups other than methyl groups. Non-limitingexamples of such groups other than methyl groups include alkyl groupsother than methyl groups, alkene groups, alkyne groups, hydroxyl groups,thiol groups, ester groups, acid groups, ether groups, wherein thegroups other than methyl groups may be further substituted.

The symbol D denotes the difunctional unit (CH₃)₂SiO_(2/2) wherein twooxygen atoms bonded to the silicone atom are used for binding to therest of the polymer. The “D” unit, which is the major building block ofdimethicone oils, can be represented as:

At least one of the methyl groups of the D unit may be replaced byanother group, e.g., to give a unit with formula [R(CH₃)₂]SiO_(1/2).

The symbol T denotes the trifunctional unit, (CH₃)SiO_(3/2) and can berepresented as:

At least one of the methyl groups of the T unit may be replaced byanother group, e.g., to give a unit with formula [R(CH₃)₂]SiO_(1/2).

Finally, the letter Q means a tetrafunctional unit SiO_(4/2) in whichthe silicon atom is bonded to four hydrogen atoms, which are themselvesbonded to the rest of the polymer.

Thus, a vast number of different silicone polymers can be manufactured.Further, it would be clear to one skilled in the art that the propertiesof each of the potential silicone polymers will vary depending on thetype(s) of monomer(s), the type(s) of substitution(s), the size of thepolymeric chain, the degree of cross linking, and size of any sidechain(s).

Non-limiting examples of silicone polymers include siloxysilicates andsilsesquioxanes.

A non-limiting example of a siloxysilicate is trimethylsiloxysilicate,which may be represented by the following formula:[(CH₃)₃XSiXO]_(x)X(SiO_(4/2))_(y)

(i.e., MQ units) wherein x and y may, for example, range from 50 to 80.Silsesquioxanes, on the other hand, may be represented by the followingformula:(CH₃SiO_(3/2))_(.x)

(i.e., T Units) wherein x may, for example, have a value of up toseveral thousand.

Resin MQ, which is available from Wacker, General Electric and DowCorning, is an example of an acceptable commercially-availablesiloxysilicate. For example, trimethylsiloxysilicate (TMS) iscommercially available from General Electric under the tradename SR1000and from Wacker under the tradename TMS 803. TMS is also commerciallyavailable from Dow Chemical in a solvent, such as for example,cyclomethicone. However, according to the present invention, TMS may beused in the form of 100% active material, that is, not in a solvent.

Suitable silicon resins comprising at least one T unit in accordancewith the present invention are disclosed, for example, in U.S. patentapplication publication numbers 2007/0166271, 2011/0038820,2011/0002869, and 2009/0214458, the entire contents of which are herebyincorporated by reference in their entirety.

Where the silicone resin contains at least one T unit, it may thus be,for example, a T, MT, MTQ or MDTQ resin.

According to preferred embodiments, the unit composition of the siliconeresin can be at least 50% T units, or at least 70% T units, or at least80% T units, or at least 90% T units.

In the M, D and T units listed as examples above, at least one of themethyl groups may be substituted. According to preferred embodiments,the at least one silicone resin comprising at least one trifunctionalunit of formula (R)SiO_(3/2) is chosen from the silsesquioxanes offormula: ((R′)SiO_(3/2))_(x), in which x ranges from 100 to 500 and R′is chosen, independently by trifunctional unit, from a hydrocarbon-basedgroup containing from 1 to 10 carbon atoms or a hydroxyl group, on thecondition that at least one R′ is a hydrocarbon-based group. Accordingto preferred embodiments, the hydrocarbon-based group containing from 1to 10 carbon atoms is a methyl group. According to preferredembodiments, the at least one silicone resin comprising at least onetrifunctional unit of formula (R)SiO_(3/2) is chosen from thesilsesquioxanes of the formula: ((R′)SiO_(3/2))_(x), in which x rangesfrom 100 to 500 and R′ is chosen, independently by unit, from CH₃, ahydrocarbon-based group containing from 2 to 10 carbon atoms, or ahydroxyl group, on the condition that at least one R′ is ahydrocarbon-based group.

In particular, suitable gelling agents for the oil phase include, butare not limited to, lipophilic or hydrophilic clays.

The term “hydrophilic clay” means a clay that is capable of swelling inwater; this clay swells in water and forms after hydration a colloidaldispersion. These clays are products that are already well known per se,which are described, for example, in the book “Mineralogie des argiles”,S. Caillere, S. Henin, M. Rautureau, 2^(nd) edition 1982, Masson, theteaching of which is included herein by way of reference. Clays aresilicates containing a cation that may be chosen from calcium,magnesium, aluminium, sodium, potassium and lithium cations, andmixtures thereof. Examples of such products that may be mentionedinclude clays of the smectite family such as montmorillonites,hectorites, bentonites, beidellites and saponites, and also of thefamily of vermiculites, stevensite and chlorites. These clays may be ofnatural or synthetic origin.

Hydrophilic clays that may be mentioned include smectite products suchas saponites, hectorites, montmorillonites, bentonites and beidellite.Hydrophilic clays that may be mentioned include synthetic hectorites(also known as laponites), for instance the products sold by the companyLaporte under the names Laponite XLG, Laponite RD and Laponite RDS(these products are sodium magnesium silicates and in particular sodiumlithium magnesium silicates); bentonites, for instance the product soldunder the name Bentone HC by the company Rheox; magnesium aluminiumsilicates, especially hydrated, for instance the products sold by theVanderbilt Company under the names Veegum Ultra, Veegum HS and VeegumDGT, or calcium silicates, and especially the product in synthetic formsold by the company under the name Micro-cel C.

The term “lipophilic clay” means a clay that is capable of swelling in alipophilic medium; this clay swells in the medium and thus forms acolloidal dispersion. Examples of lipophilic clays that may be mentionedinclude modified clays such as modified magnesium silicate (Bentone GelVS38 from Rheox), and hectorites modified with a C₁₀ to C₂₂ fatty-acidammonium chloride, for instance hectorite modified withdistearyldimethylammonium chloride (CTFA name: disteardimoniumhectorite) sold under the name Bentone 38 CE by the company Rheox orBentone 38V® by the company Elementis.

It is in fact possible to modifythe surface of silica chemically, by a chemical reaction producing adecrease in the number of silanol groups present on the surface of thesilica. The silanol groups can notably be replaced with hydrophobicgroups: a hydrophobic silica is then obtained. The hydrophobic groupscan be:

trimethylsiloxyl groups, which are notably obtained by treatment ofpyrogenic silica in the presence of hexamethyldisilazane. Silicastreated in this way are called “Silica silylate” according to the CTFA(6th edition, 1995).

Testing Protocols

Gloss Testing

Samples were evaluated for their gloss value using a gloss meter. Samplefilms were prepared by using a 3 mil wet drawdown bar to deposit a filmonto BYK Opacity Chart (#2812). Films were allowed to dry for a minimumof 1 hour and then were evaluated for their gloss values using a BYKMicro-TRI-Gloss meter. From the values captured, the 60 degree value wasreported. A value of less than 10 GU was considered to be low gloss; avalue of 10-69 GU was considered to be medium gloss; and a value of 70GU or greater was considered to be high gloss.

Transfer-Resistance: Kiss Test

Samples were tested for their resistance to transfer. The samples wererespectively applied by a subject and allowed to dry for 15 minutes.Following the 15 minute dry time, each subject kissed their clean backhand and an image was captured to assess level of transfer. For fulltransfer, a score was given of 3, while somewhat transfer was given ascore of 2, and little to no transfer was given a score of 1.

Self-Leveling Testing

Samples were evaluated for their dried film properties. Samples werecasted onto a BYK Opacity Chart (#2812) using a 3 mil wet drawdown barat room temperature. Samples were allowed to dry for a minimum of 5hours. After drying, samples were visually and manually evaluated forphase separation and self-leveling properties. In order to assess thephase separation, films were agitated with a gloved finger with force of35-55 grams of force. In order to insure the same force was applied forall samples, the contrast card was placed on an scale, a weight itplaces to hold down the film and the scale is tarred. Then a glovedindex finger was used to pass across the sample. The pressure appliedwas sustained within 35-55 g of force. If samples could be roughened itwas documented and they were further assessed for recovery of the filmby self-leveling. Samples were allowed to rest for a minimum of a 24hour period and then visually reassessed for interface quality and ifthere was any level of recovery. Images were also captured of thesamples prior to roughening, at initial roughening, and at 24 hoursafter roughening. After the 24 hour period, it was documented if thesample showed signs of recovery or not.
